Explain how the separation of cream …

The process of centrifugation is used in dairies to separate cream from milk . 
Centrifugation is a method for separating the suspended particles of a substance from a liquid in which the mixture is rotated at a high speed in a centrifuge machine.
The milk is put in a closed  container in big centrifuge machine .
when the centrifuge machine is switched ON,  the milk is rotated at very high speed in a container. 
Due to this process, milk separates into cream and skimmed milk. 
The cream being lighter floats over the skimmed milk

Milk is a suspension of tiny droplets of oil (cream) in a watery liquid. The process of centrifugation is used to separate cream from milk. The milk is put in a close container in big centrifuge machine. When the centrifuge machine is switched on, the milk is rotated (or spun) at a very high speed in its container. The centrifugal force acts on the milk and due to this, the milk separates into cream and skimmed milk. The cream, being lighter, floats over the skimmed milk and can then be removed.
